My invention relates to combination-tools, and particularly to animprovement upon the tool shown and described. in Letters Patent No.530,419, granted to me December 4, 1894.

'lheobj ect in view is to construct a-tool of adjustable orinterchangeable parts or members which may be arranged to adapt thesameto performvarious functions, and particularly to improve theconstruction of the device in the matter of the screw-drivingmember, thebit and wrench-brace, the benchvise, including the means forv itsattachment to a bench, the wrench-head, and the coperating parts. l

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out'in the appendedv claims.

In the drawings, Figure 1 is aview of a tool constructed in accordancewith my invention arranged for use as a bit and wrench-brace. Fig. 2 isa sectional view of the same. Fig.

Fig. 6 is a view of the tool arranged for use asa glass- Fig. 7 is atransverse section on the line 77 of Fig. 1 to showthe latch for securing the handle against rotation. Fig. 8 isaperspective view of the device arranged for use as a bench-vise.

Similar numerals of reference indicate corresponding parts in all thefigures ofthe drawings.

1 ldesignates a cross-sectionally angular shank, terminating at itsouter end in a preferably integral fixed jaw 2, forming one member ofthe wrench-head, and fitted to' slide upon said shank is the movable oradjustable jaw 3, actuated by a feed-.screw 4, swiveled in thecross-head 5 at the inner endet' theshank. In order to adapt the-wrenchfor right and left handY use, the wrench-head is extended in oppositedirectionsrfrom the shank to form the main and auxiliary fixed jaws 2and 2b and the main and auxiliary movable or adjustable jaws 3a and 3b.The innersurfaces or faces of themain fixed and movable jaws arechanneled, as shown at 6, to receive a bit 7, as shown in dotted linesin Fig. 2.

The feed-screw 4 terminates at its inner end in a thumb-head 8, havingarms or ears 8a and 8b, which are respectively constructed to form aglass-cutter and a can -opening blade. For this purpose a diamond-wheel9 is set in a bifurcation in the ear 8a, and said ear is provided with abreaking-.notch 10 to receive the edge of the glass after the scoringthereof by the wheel. The outer edge of the ear 8b is reduced to form ablade, and the should-ers 11 of the thumb-head form rests to bear uponthe top of the can or other article to be opened.V Inasmuch as theseshoulders are arranged upon both sides of the plane of thecanopeningblade or ear 8b, it is obvious that the can-opener is adapted for eitherright or left hand use.

VThe cross-head 5 is provided with perpenvdicularly-disposed screw-studs12 and 13, the former of which is perpendicular to the plane f of thecross-head, a'nd hence parallel with the shank'of thetool, and thelatter is' formed as an extension of the cross-head, and hence isperpendicular to the shank, the end of the cross-head contiguous to the'stud 13 being broadened to form a securing ear or rest 14,` providedwith perforations 15, through which fastening screws or nails may bedriven, as indicated in Fig. 8, to fasten the portion of the toolalready described to a bench 16, and thus adapt it for use. as abench-vise. The extremities of the auxiliary portions 2f and 3a of thejaws form a rest to coperate with the rest 14 to steady the apparatuswhen used as a vise.

The handle portion or member 17 of the IOO and bit respectivelyprojecting beyond the contiguous extremities of the grip. The inner endof the bore of the tubular body portion of the handle is threaded toform a socket. for the reception of either of the threaded studs 12 and13 on the cross-head of the tool, and when the handle is attached to theciosshead by means of the stud 13, as shown in Fig. 3, the tool isadapted for use as a straighthandled wrench or by reversal as along-liandled screw-driver, in which case the wrenchliead forms a grip.In order to adapt this wrench-head to perform its function as aconvenient grip in manipulating the long-liandled screw-driver, theexposed or upper and lower sides, respectively, of the fixed and movablejaws are rounded, as shown. The movable jaw is adapted to be adjustedoutwardly to the limit of its movement when the device is to be used asa long-handled screwdriver. IVhen the tool-handle is detached, as shownin Fig. 4, it forms a sliort-handled screudriversuitable for light workor for use under conditions precludin g the employment of thelong-liaiidled tool. (Illustrated in Fig. 3.) The milling of theperiphery of the disk at the inner end of l[he body portion of thehandle provides the proper grip by which the bit may be turned, andinasmuch as the bit is integral with the body portion of the handle itmay be made of sufficient strength to resist any strain to which it maybe subjected.

IVhcn the socket in the inner end of the handle is engaged with the stud12, as shown in Fig. 5, the device is adapted for use as an S-wrench-adesirable form of the tool for certain classes of work in connectionwith which the ordinary or straight-handled form of wrench shown in Fig.3 is inoperative. IVhen the handle is arranged at right angles to theshank by its engagement with the stud 12, it is desirable to secure thehandle-body portion or spindle from rotation, and the means which Iemploy for accomplishing this object consists of a latch having aspring-aetuated bol 22, mounted iii an open-ended sheath or guide 23,preferably integral with the cross-head and parallel with the stud 12,for engaging a perforation 21 in the peripherally-milled disk at theinner end of the handle. This bolt is reduced at one end, as shown at25, to form a shoulder 26, between which and the inner end of the guideis arranged a coiled spring 27, the parts being held in said position bythe permanent attachinent of a thu mb-hold 2S to the inner extremity ofthe bolt, said thumb-hold serving to limit the extension of the boltunder the tension of its actuatiiig-spring.

In Figs. l and 2 I have shown the tool arranged for use as a bit andWrench-brace, in which case the wrench-head and connected parts and thehandle are arranged, as shown in Fig. 5,with the handle in engagementwith the stud 12 or perpendicular to the shank, and applied to the outerend of the handle is a brace-arm 2f), provided with a ciossscc tionallyangular terminal socket 30, which is adapted to fit upon and forni asheath for the screw-driver bit at the outer end of the handle. Thus thescrew-driver bit performs, in addition to its usual function, that of astud for the attachment of the brace-arm, and by tapering thescrew-driver bit the brace-arm may be driven to place thereon to form asu ffi ciently firm attachment of the parts.

From the above desci'iption it will be seen that the screw-driver bit ispermanently attached to the body portion of the handle and is adapted toperform its function as a screwdriver when exposed by the removal of thebrace-arm and either detached from the shank or attached paralleltherewith, as shown, respeetively, in Figs. 4- aiid IVhen the handle isdetached from the shank, the latter may be attached to a bench for useas avise or maybe reversed to perform its function as a glass-cutter orcan-opener. The rest,whicli is formed upon the extremity of theeiosshead and parallel with the shank to bear upon the bench, is locatedat the saine distance from the shank as the extremity of that portion ofthe wrench-head which is upon the same side of the shank, or thatportion of the wrench-head formed by the auxiliary fixed and movablejaws. Thus when the device is arranged for use as a bench-vise the faceof the rest and the extremity of the short end of the Wrench-head bearupon the surface of the bench, the additional bearing formed by theshort arm of the wrench-liead serving to steady the device and relievethe securing means of strain.

The advantage of the manner of mounting the latch resides in the factthat the spring and contiguous portion of the sliding bolt are whollyconcealed Within the sheath and are thereby protected from moisture toprevent accumulations of dust and rust from rendering the latchinoperative.

Some of the uses of the tool embodying my invention have been abovedescribed; but it is obvious that its parts or members are capable ofnumerous relative arrangements and are adapted to perform functionswhich it is unnecessary to explain herein in detail; and it will beunderstood, furthermore, that various chan ges in the form, proportion,and the minor details of construction may be resorted to withoutdeparting fi'oin the spirit orsacrificin g any of the advantages of myinvention.
